Settin
g Homing direction Homing methods Description
-1 Forward rotation (CCW)
or positive direction Dog type (Rear end detection - Z-phase reference) Performs homing using the Z-phase pulse after a moving
part has moved past the proximity dog.
Deceleration starts from the front end of the proximity dog.
After the rear end is passed, the position specified by the
first Z-phase signal or the position of the first Z-phase
signal shifted by the specified home position shift distance
is used as the home position.
-2 Count type (Front end detection - Z-phase reference) Performs homing using the encoder pulse count after a
moving part came into contact with the proximity dog.
Deceleration starts from the front end of the proximity dog.
After the front end is passed, the position specified by the
first Z-phase signal after the set distance or the position of
the Z-phase signal shifted by the set home position shift
distance is set as the home position.
-3  Data set type Performs homing without a dog.
The current position is set as the home position.
Homing can be executed in the Operational enabled state.
Homing cannot be executed in the servo-off status.
-4 Forward rotation (CCW)
or positive direction Stopper type (Stopper position reference) Performs homing with a workpiece pressed against a
mechanical stopper.
A workpiece is pressed against a mechanical stopper, and
the stop position is set as the home position.
-6 Dog type (Rear end detection - rear end reference) Performs homing with reference to the rear end of the
proximity dog.
Deceleration starts from the front end of the proximity dog.
After the rear end is passed, the position is shifted by the
travel distance after proximity dog and the home position
shift distance. The position after the shifts is set as the
home position.
-7 Count type (Front end detection - front end reference) Performs homing with reference to the front end of the
proximity dog.
Deceleration starts from the front end of the proximity dog.
The position is shifted by the travel distance after the
proximity dog and the home position shift distance. The
position after the shifts is set as the home position.
-8 Dog cradle type Performs homing using the first Z-phase pulse with
reference to the front end of the proximity dog.
The position specified by either the first Z-phase signal
after the front end of the proximity dog is detected or the
position of the first Z-phase signal shifted by the home
position shift distance can be set as the home position.
-9 Dog type last Z-phase reference Performs homing using the last Z-phase pulse with
reference to the front end of the proximity dog.
After the front end of the proximity dog is detected, the
position is shifted away from the proximity dog in the
reverse direction. Then, the position specified by the first
Z-phase signal or the position of the first Z-phase signal
shifted by the home position shift distance is used as the
home position.
-10 Dog type front end reference Performs homing with reference to the front end of the
proximity dog in the direction of the front end.
Starting from the front end of the proximity dog, the
position is shifted by the travel distance after the proximity
dog and the home position shift distance. The position
after the shifts is set as the home position.
-11 Dogless Z-phase reference Performs homing with reference to the first Z-phase in the
direction of the dog front end.
The position specified by the first Z-phase signal or the
position of the first Z-phase signal shifted by the home
position shift distance is used as the home position.
